HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,165, dated October29, 1889.

Application filed February 12, 1889- Serial No. 299,597- (No model.)

To all who/2t it may concern:

Be it known that I, MARION L. NICHOLS, of New York, county of New York,State of New York, have invented new and useful Improvements inHarvesting liachines, of which the following is a full and exactdescription, reference being had to the accompanying drawings, makingpart of this specification.

My invention relates to that class of machines supported upon three ormore wheels, and in which the grain is carried to the binding devicesbetween the master and the front supporting wheel; and the inventionconsists in connecting the master-wheel frame rigidly with the mainframe of the machine and the front supporting-wheel thereto throughasaddle or frame and rocking levers, and in connecting the wheehframe tothe saddle through a swivel-connection, whereby, while permitting theready adjustment of the cutter or the raising and loweringof the same,the said supporting-wheel is free to be turned on a vertical axisindependent of the connecting-levers to facilitate the turning of themachine.

In the accompanying drawings, Figure 1 is a plan or top view of so muchof a harvesting-machine as is necessary to show my improvement and withthe canvas or apron removed. Fig. 2 is a perspective view of the frontsupporting-wheel, showing the manner of connecting the same to the mainframe through the saddle and the levers, by which the relation of themachine to said front supporting-wheel is changed or adjusted. Fig. 3 isa perspective view of a portion of the rear frame-bars of the machine,showing the angleframe connected thereto and the master-wheel frame.Fig. 4: is an end view of the frame, showing the grain-W11 eel, its arm,and the means for connecting said arm to the main frame.

The main frame is made in oblong rectangular form, having the rearframe-bars A A, front-sill or angle barA, cross-bars A longitudinal barA and end frame-bar A The rear frame-bars A and cross-bars A arepreferably made of metal tubing or gas-pipe, while the front sill ismade in the usual angle form, to which the fingers are attached. Therear frame-bars A A have connected thereto, adjacent to the crossbars Aan angular frame B, having bearings b b 21 formed therein for thedifferent shafts from which motion is communicated to the variousmechanisms for cutting, delivering, and binding the grain. Themaster-wheel frame D is connected to this frame B through end bolts (1,engaging the bars thereof, and lugs or cars 01, formed with said frameB, and by a central bolt (1 engaging a flange d depending from the lowerface of said frame B; and said master-wheel frame consists of the sidebars D D, connected with the central cross-bar to form an openendedframe, and in the ends of the side bars D D are formed or connected thebearings for the axle E of the masterwheel E. Brace-rods F are connectedto the side bars D D and to the frame B to strengthen and form a morerigid connect-ion between the frames B and D.

The front-sill or angle bar A has mounted thereon, near the inner end ofthe cutting apparatus, a lifting-post G, hereinafter referred to. Aframe or horn H, bent at its inner por tion to conform to the shape ofthe liftingpost, is provided with arm H, through which it is secured toa forwardly-extending portion of the bar A by means of a bolt h, andhaving a similar connection with the frame on the opposite side. (Notshown.) The frame or horn is provided with the arms which extend outfrom each side of the lifting-post and curved upward and outward, andhave formed at their upper ends bearings or jour nals h, 011 which thelifting levers (hereinafter referred to) are mounted.

The front supporting-wheel frame Ihas the tongue rigidly connectedthereto, and is provided wit-h depending arms I, in the lower end ofwhich are formed the bearings for the axle l of the frontsupporting-Wheel I EX- tending from the upper face of the Wheelframe Iis a pivot pin or journal 1 and on which journal is mounted saddle K,straddling the wheel-frame, and to the depending arms of which saddleare connected levers K, the journals or the fulcrums of which are formedin the arms 11, and which levers extend back and have theliftingchains Kconnected thereto, the said chains passing up over a roller K mounted insuitable bearings in the liftiug-post and being connected to a readyturning of themachin'e.

wheel and main frame when said wheel has shaft or 'windlass K alsomounted in bearings in the lifting-post, and which shaft or Windlass isrevolved to Wind the chain thereon by any suitable mechanism, preferablya worm and gear K K as shown.

A lug L is formed onthe wheel-supporting frame to the left of the centerof the journal or on the opposite side from the cutters, and to whichlug is connected a stayor stop chain 1 L, which is in turn connected toan eye or bolt secured to the lifting-post to connect the wheel-frameswith the main frame, the'obj eat of which chain is to prevent the tonguefrom being thrown too far around toward the 'cutters and reel in turningthe machine and to form a brace or fixed connection between the beenturned suffi'ciently far to permit the The grain-wheel M is mounted onthe end of a bell-crank lever or arm M", connected to e the main frameabout centrally of the width of the machine from front to rear.

The operation of the several parts will be readily understood, and [suchparts as are shown and not particularly described herein, as also theparts of the machine to complete 1 the harvester and binder, may beconstructed I in any preferred manner.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

g 1,111 a harvester, the combination of the front supporting-wheelframe, a saddle with which the front-wheel frame has aswivelconnec-t-ion, and levers connected to the saddle and to the mainframe for changing the relation of the cutters to the ground.

2. In a harvester, the combination of the master-wheel frame having arigid connection with the main frame, a front supporting- Wheel framehaving the tongue rigidly connected thereto, a saddle to which the frontsupporting-wheel frame is swiveled, and levers connected to the saddleand to the main frame for changing the relation of the cutters to theground, substantially as set forth. 3. In a harvester, the combinationof the front supporting-wheel frame, a saddle to which the wheel-fir menswiveled, and levers connecting the mainframe and saddle for raising andlowering the cutters, and a staychai'n uniting the main frame andwheelframe fonvlimitingthe swivel movement of the wheel-frame relativeto the saddle, substantially as set forth.

In testimony whereof I have hereunto 'set my hand this 9th day ofFebruary, A. D. 1889.
